Unbiased comparison of ap1/ap2 wanted

There is no such thing as Fact based on personal preference.
The fact that they like the AP2 is their opinion and opinion only. Stating "factual information" based on opinion, no matter how many people, makes you look foolish.
WTF are you smoking?

This brings up an interesting point though, we should make a poll...
Which is the best
[] AP1
[] AP2
We could even do the following, sense we'll be arguing about this next year:
Which is the best
[] 00-01
[] 02-03
[] 04-05
[] 06-07

Spend enough time doing freeway lane changes in both and you'll notice the difference.
Further, I'm not absolutely sure that the AP1 does turn in more quickly. There is a difference in the way it settles into a turn (a hard turn, like when I'm autocrossing) that goes beyond the difference in the amount of oversteer, but I think to the extent that it might *feel* quicker, it might just be an illusion. In any event, the AP2 has steering that is quick enough to be as much fun as any AP1.
In either chassis you can drive along in a straight line, then give the steering a quick yank (which is bad driving technique, fwiw), and the front tires will bite making the car change direction almost instantly. Fact is, the WAY you turn in will make a bigger difference in the way the car responds than the chassis you're driving. Either car can be made to oversteer, or understeer, on turn in, and either can can be trail braked right up to the apex of a turn without having either end wash out.
The AP1 *may* turn in quicker under some conditions, but to the extent that it does, or even to the extent that it feels like it does, it's just a result of some changed compromises, not something that is limp in the AP2. Pick two S2kI visitors (who do not own an S2000) and put them on a track in bone stock like new cars, and AP1 and an AP2, and if the two drivers have equal skills I think everyone here knows which car would turn the quickest times. Swap the cars and the same car would be faster for both drivers, and it would be pretty odd if that car was the AP1.
Man, our AP1's break if we put R compound tires on them and autocross them too much. Does that happen with the stiffer, improved, AP2 chassis?
(I don't actually know, but it seems like a fair question.)
You may be right, and freeway lane changes might expose a difference, but do you really think it's a difference that makes or breaks the car?
I think it's just a tiny difference, if that, that people like to argue about.

The formula that is used to compute HP favors torque at high RPM over torque at a lower RPM.
HP = (rpm*torque)/5252
If the F22C Makes 137 ft/lbs of torque at 8000 you get 210whp, and it continues constant to 9K, you'd get 234whp. torque would have to fall to 122 before you start loosing HP.
So torque would have to fall through the floor in order for the F22 not to make more power at 9000 rpms. Remember each time you change gear, you loose torque at the wheels.
But even with the a loss of torque 1st gear's ratio is 3.133 and second is 2.045, so staying in 1st for another 1000 rpms gives you a 50% torque advantage for that time.

There has to be some other reason for the lower redline, and I think Billman has it pegged.
Do you have any idea how quickly the engine falls off the F22C cams above 8k? Does it drop like a rock or just taper off?
